As Labor MPs head back to their electorates to lick their wounds, the Opposition Leader has warned the Coalition will try to move a motion of no confidence in the Government when Parliament resumes on May 14.

He told AM the Opposition would need support from all seven crossbenchers in the Lower House for the motion to pass, a result which would trigger an election.

"We've still got a Government which is paralysed. We've still got a civil war inside the Government," he said.

"It will be up to the independent members to look into their consciences, to consult with their electorates.

"I think their electorates will say, we want the people to choose the government and the prime minister. We are sick of backroom deals. We're sick of the faceless men."

A vote to hold a motion of no confidence in the Prime Minister failed to pass the House of Representatives amid the turmoil yesterday because it did not get an absolute majority.

But this morning independent Tony Windsor said he backed Mr Abbott's "right" to test the waters with a wider motion of no confidence in the government itself.

"I said to Tony Abbott over the last two-and-a-half years, if you think the House doesn't have confidence in the Prime Minister or the Government, test the marketplace," he said.

"That's the first time yesterday that he's actually attempted to do that.

"If he does it again, I will support his right to seek leave to test the confidence of the House.

"I want to see it tested too. Let's see how the numbers stack up. Obviously he will probably do that next time the Parliament resumes."

But Ms Gillard dismissed the no-confidence threat when she spoke to ABC Melbourne's Jon Faine this morning.

"I've heard Mr Abbott huff and puff about no confidence motions on many occasions and it never comes to anything," she said.

"By the time we come back in May we won't hear anything more of it."

Ms Gillard said the message from yesterday was that the leadership issue was "over, it's clearly over".

"There was an opportunity, the opportunity wasn't used," she said.

"Anyone who comes into a journalist's office in the future from the Labor party claiming to have the numbers will be met with gales of laughter."

Ms Gillard said she was working on the reshuffle and "there will be a few more people considering their position".

Speaking from Washington DC, Foreign Affairs Minister Bob Carr said he expected Ms Gillard's position to be made stronger after the events of Thursday.

Offering his "unqualified support" for Ms Gillard, he said: "I think she has renewed and affirmed her leadership."

Treasurer Wayne Swan said the Coalition threatened the no-confidence tactic repeatedly, without success.

"This is the tactic that [Mr Abbott] used for about the first year of the life of the Government - almost every day in the House moving a suspension of standing orders which he could never win," he said.

"And that's all that happened yesterday. He had the hide to claim in the media yesterday there was some sort of vote on confidence in the House. That is simply not true."
